PROCESS FOR ACETYLATION OF WOOD IN THE PRESENCE OF AN ACETYLATION CATALYST

摘要

The present invention describes a process for the acetylation of wood comprising treating wood with an acetylation agent comprising acetic anhydride and/or acetic acid and subjecting to acetylation conditions, wherein the acetylation reaction is carried out in the presence of an acetylation catalyst comprising a salt of an organic acid, wherein the organic acid is a carboxylic acid, phenol or a substituted phenol, wherein the carboxylic acid is chosen from the list consisting of aromatic carboxylic acids, medium chain saturated monocarboxylic acids, keto acids, dicarboxylic acids, tricarboxylic acids, hydroxy acids, amino acids and derivatives thereof.
